So, you are allowed to criticize the sampling issues of others, but others aren't allowed to criticize your sampling issues?

How shameless can you be?

I don't know. I've not heard any anecdotal reports along the lines of, "If only I'd agreed to have sex with Mr. Jones when I was 10, I would have been sexually fulfilled and life would have been so much better!" It certainly could be tested with questionnaires.

I have heard that aplenty. It is just that, unlike the presence of early sex, the absence of early sex is not used as a metanarrative to explain everything which is wrong in the present. So neither the MHPs, nor the people themselves, whether or not they are seeing an MHP, use it as a pretext for anything.

It certainly can be studied by interviewing men and girls independently about the same experiences.

No it can't.

At least not under your standards. Where she can never prove that she is telling the truth. And you don't give a damn anyway.

also would include understanding that a failure to object or struggle is not enough to mean consent.

Funny that this is absolutely the only place in law where that happens.
